Guest Invoicing Modifications Follow

Note that when a reservation gets modified (Due to: date change / number of guest change/ amenity change for extra charge) it does not modify the invoice nor automatically charge the guest credit card with the additional charge that occurs due to the modification. 

In these cases you have to modify the invoice and the charge (if charge not triggered yet) or you may create a new invoice (How to create manual invoices?). If there is deduction in the reservation total, this needs to be amended on the invoice (If the invoice is already triggered you may refund the guest the balance via stripe). 

Solution 1: Modify the current invoice and the charge: 

Step 1: Go to Reservations> Locate the reservation via "More Filters"> Find the new Reservation Total:

Step 2: Scroll down to Invoices and charges section> Check the amount which the system is scheduled to charge the guest> If the reservation total does not equal to the charge amount, click on "Edit" in order to edit the charge amount:

Step 3: Update the charge amount> Hit "Update":

Solution 2: Create a new invoice for the additional amount occurred due to reservation modification (How to create manual invoices?)

You have 2 ways of creating a single invoice. You can create an invoice from the Guest Invoicing feature > Invoice > Add

Or create an invoice from a reservation
